unless you are someone who has auto hide taskbar on...in which case it was throwing an error about the bar already being hidden and then turning off the option...every time my laptop turned off or I cycled back to it on my hdmi switch...ffs
Generally, as my boss will tell you, I don't use laptops, tho I did play around with auto-hiding the taskbar when it was first installed and still didn't like it :/ but never saw an issue when I was using it on my desktop. Just for reference, my 3rd monitor is actually a TV that is used for gaming systems via an HDMI switch.
but I would take not being able to use auto-hide over the seizure-inducing way prior versions of windows had of dealing with monitors disconnecting any day
